About this app

Tuning isn't a task, it's the ten-second obstacle between you and the music.

This app exists for those ten seconds, and only those. You tap the icon and it's already listening. You touch the string, the note appears giant on the screen, the pointer moves. When it's in tune, it turns green and the phone vibrates in your hand. Ready. You can go back to playing.

SEVEN INSTRUMENTS, ONE APP

Guitar. Electric guitar. 4-string bass. 5-string bass. Brazilian viola. Cavaquinho. And a chromatic mode for everything else.

Switching from one to another is a tap. If you play guitar at home and bass at rehearsal, if you teach and each student arrives with an instrument, if your samba circle has cavaquinho and viola: it's the same app.

BRAZILIAN VIOLA AS IT IS

Cebolão in E, Cebolão in D, Rio Abaixo and Boiadeira. All four on the screen, one tap each.

And the octave pairs appear perfectly. The three bass pairs have a thin string that sounds an octave higher than the thick one, and the app recognizes both. Play the thick string, it tunes the thick string. Play the thin string, it tunes the thin string. You go through all ten strings without guessing anything.

SAMBA AND CHORO CAVAQUINHO

D, G, B, D, the way it's tuned in Brazil. The old tuning, with E on the first string, is also there.

GUITAR, BASS AND GUITAR

Standard tuning, Drop D and a half step down. On the five-string bass, the drop is the real one: the B goes down to A.

A half step down appears written as you write it, in flat: E♭, not D♯.

TUNES ITSELF, WITHOUT YOU CHOOSING THE STRING

You don't need to tell the app which string to tune. Play any one and it finds it. The string lights up on the track below the screen, and the ones you've already tuned are marked, so you can see at a glance how much is left.

From the moment you open it until the instrument is tuned, your hand doesn't leave the fretboard.

DO RE MI, IF YOU WANT

You learned that that note is G. Here it appears as G, and you don't translate anything from memory with the instrument in your hand and the rehearsal starting.

An option in the settings changes the entire screen: the large note, the string track, and the tuning name. If you prefer the letter, it's already the default and you never need to open that screen.

PREVENTS YOU FROM BREAKING A STRING

A new string is still loose and sounds well below its place. That's when the accident happens: you tighten the tuning peg in the direction of the wrong note and the string breaks.

This app notices that you are an octave off, hides the pointer, and tells you what the real note is. One saved string already pays for the app.

MADE FOR THE STAGE AND FOR THE DARK

The note is large enough to read from an arm's length away, with your phone on the floor and the lights off. The screen doesn't turn off automatically while you tune.

And because it vibrates when the string goes into tune, you can tune without looking at your phone.

CHROMATIC MODE FOR EVERYTHING ELSE

Mandolin, banjo, violin, ukulele, an instrument no one predicted. In chromatic mode, the app doesn't search for any string: it shows the note that's sounding and how much is left to reach the correct pitch.

ADJUSTMENTS FOR THOSE WHO NEED THEM

The reference A ranges from 430 to 450 Hz, for those who play wind instruments, with an orchestra, or accompanying old recordings. And you can tighten or loosen how much deviation it accepts before saying it's in tune.

If you don't need any of that, the adjustments are already correct. NOTHING BLOCKED AND NOTHING IN THE WAY

No ads. No subscription. No registration. No splash screen. No notifications asking for a rating. No hidden features behind a paid version, because there is no paid version: you've already bought it.
